Benign cystic Teratoma and Gonadoblastoma developed in bilateral abdominal undescended testis

Abstract

Cryptorchidism is one of the most common congenital malformations in humans and one of its most important consequences is the development of testicular cancer. While germ cell tumors (GCTs) and sex cord-stromal tumors are major testicular tumors. Gonadoblastoma is a rare neoplasm composed of a combination of germ cells and gonadal stromal elements. In this study we present a patient with bilateral abdominal undescended testis with gonadobelastoma in the left and benign cystic teratoma in the right testicle.
